Q:thermodynamic question that includes heating water with solar panels?

Q:what is the cost of a solar panel
With out the kW information of the need for your workshop no one can really tell you what you need for power supply. I would recommend you orientate your building or shop to maximize the passive solar potential. this will drastically eliminate your excessive need for heating and cooling. Which in turn will maximize your solar energy from the panels. Also depending upon what state you live in do some further research into any programs or grants offered by the power companies or state incentives. Regarding hydrogen...for get about it.

Q:help setting up a solar panel system?
That okorder.com/... , but expect to pay several thousand dollars for something that actually works. If you just want to use the place for intermittent getaways, a generator may be sufficient, and you can skip the solar panels. If you intend to live in the place, then consider getting a system that is at least 500-000 watts of panels, and a 000 amp-hour or more battery bank.
Q:How many solar panels?
A laptop is about 70 to 00 W, and you have two. You also may need to power a router, and modem. So, about 50W to 250W contineous should cover it. To save power when not in use, you can let the display go blank. This will reduce your solar pannel, and battery size, and cost. You will need batteries, and blocking rectifier to store the energy for use at night, and a 300W to 400W inverter. Checkout the link below for purchasing solar equipment. You can only hope to get about 8 to 9 hours of full output from your solar pannels, and 80% efficiency. The laptops will be on and using about 200W for the 8 hours during the charging period. So your pannels, need to produce that plus 2 times more than this amount, so you can charge the batteries for the evening, at the same time. So for 24 hour operation, you will need 200W x8hrs for the laptops, plus (6 hours*70W)/8=340W avg. Total of ~540W for 8 hours. Assuming you use power saving modes when not in use, you can probably get away with 3x60W -- 520W to 600W pannel. ( Thuja is right, a few cloudy days may knock you offline) Batteries. A common low cost ( $40) automotive battery can hold about 40 Amp/hours at 2V. Under load, you may get 35 Amp hours at 0V, which is about 350Watts for one hour. You need about 80W avg for 6 hours, or ~ 2900Watt Hours. Which means you would need 9 automotive batteries. Deep storage batteries cost more, but are more durable. 6*00W pannels, $460*6 ~ $2800 Inverter $70 Batteries $400 Battery cables, rectifier, lugs, connectors $50 There are probably some other hidden costs. I was rooting for you, but it appears to be pricey. Another thing you can do, is to use the new energy efficient RF florescent bulbs for lighting. The color and brightness are excellent, and a 60W bulb only uses about 3W, and they last a lot longer as well.
Q:Does infrared radition occur in solar panels?
- Radiation from the sun is mostly Ultra- Violet. - There are 2 types of solar panels, Solar thermal collectors and photovoltaic cells. - Put simply, photovoltaic cells take the UV rays and produce electricity. - Solar thermal collectors (which is probabl
Q:How Solar Panel Works ?
when sunlight hits a solar panel the photons from the light hit a layer in panel that converts it into electrons through conduction, thus making electricity
Q:how long do roof solar panels last?
Ive been using the same solar panels for 5 years, have move a few times so they last a lot longer than the roofs weve had over us. I am teaching my kids how to build wind generators, because we keep having power failiures when the wind blows. and recently its got very windy. I charge banks of battery's and keep my office running from dc-ac converters.
Q:A good brand of solar panels for my house?
I didn't research this. I do know that you must install them on the side or area of the roof that receives the most Sun all day. You can get information at stores like Lowes or HomeDepot.
Q:how to make your own solar panel?
try adding more solar panels to your car, what if you take the solar panels out of 2 or 3 calulators , add them, then use some tiny mirrors to help draw more light into the panels,.--------------------------------... solar cell (or a photovoltaic cell) is a device that converts photons from the sun (solar light) into electricity. In general, a solar cell that includes the capacity to capture both solar and nonsolar sources of light (such as photons from incandescent bulbs) is termed a photovoltaic cell. Fundamentally, the device needs to fulfill only two functions: photogeneration of charge carriers (electrons and holes) in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity. This conversion is called the photovoltaic effect, and the field of research related to solar cells is known as photovoltaics. Solar cells have many applications. Historically solar cells have been used in situations where electrical power from the grid is unavailable, such as in remote area power systems, Earth orbiting satellites or space probes , consumer systems, e.g. handheld calculators or wrist watches, remote radiotelephones and water pumping applications. Recently solar cells are particularly used in assemblies of solar modules (photovoltaic arrays) connected to the electricity grid through an inverter, often in combination with a net metering arrangement. Solar cells are regarded as one of the key technologies towards a sustainable energy supply.
